Compressive sensing based secure data aggregation scheme for IoT based WSN applications

Compressive Sensing (CS) based data collection schemes are found to be effective in enhancing the data collection performance and lifetime of IoT based WSNs. However, they face major challenges related to key distribution and adversary attacks in hostile and complex network deployments. As a result, such schemes cannot effectively ensure the security of data. Towards the goal of providing high security and efficiency in data collection performance of IoT based WSNs, we propose a new security scheme that amalgamates the advantages of CS and Elliptic Curve Cryptography (ECC). We present an efficient algorithms to enhance the security and efficiency of CS based data collection in IoT-based WSNs. The proposed scheme operates in five main phases, namely Key Generation, CS-Key Exchange, Data Compression with CS Encryption, Data Aggregation and Encryption with ECC algorithm, and CS Key Re-generation. It considers the benefits of ECC as public key algorithm and CS as encryption and compression method to provide security as well as energy efficiency for cluster based WSNs. Also, it solves the CS- Encryption key distribution problem by introducing a new key sharing method that enables secure exchange of pseudo-random key between the BS and the nodes in a simple way. In addition, a new method is introduced to safeguard the CS scheme from potential security attacks. The efficiency of our proposed technique in terms of security, energy consumption and network lifetime is proved through simulation analysis.

The novelty of the work is moderate.
We have revised the paper to highlight the significance of the proposed scheme and create a separate subsection called Motivation and Contribution please see section 1.1 The authors should give the brief explanation about the IoT enabled WSNs in the introduction.
The paper is revised for better understanding and the details about IoT enabled WSNs are provided in introduction: lines 5-12 Why the authors keep the title as IoT enabled WSNs? now, and we changed it into IoT based WSNs instead of Fixed, the title is revised IoT enabled WSNs The authors should make formal security analysis.
Thanks for the valuable comments, we have modified the security analysis section accordingly. Please see section 5.1

Paper needs to polish and provide a detailed explication of theoretical aspects such as conditions and theorems, and practical issues like algorithms, rules and possible applications.
Fixed, we have done a major revision of the language as well as the flow of the paper for better readability and understanding Introduction section needs to be re-written to improve its quality and readability.
Fixed, this section is now revised to improve the readability and understanding Improve the quality of figures and explain those properly.
Fixed, the figures are redrawn with better quality Following are some of relevant and recent references which need to be discussed in the revised manuscript: Many references are with incomplete bibliographic information (like lack of publication venue, for instance). This must be corrected. There are many English and grammatical issues in the paper which needs to be rectified.
Fixed, we have done a major revision of the language as well as the flow of the paper for better readability and understanding The formula character format is best to be different from the main text, and mathematical characters are recommended. In the related works, "et al" should be "et al.".

It seems that the contribution points of the article are a little bit few. After or in the section of Motivation, it is recommended that the authors summarize the contribution points of their work, which clearly demonstrate the innovations.
